Answer:
The total is 97/100
Step-by-step explanation:
47/100+3/100=50/100 (aka 1/2)
50/100+47/100=97/100

Step-by-step explanation:
<u>Step 1: Define Systems</u>
5x + y = 9
10x - 7y = -8
<u>Step 2: Rewrite Systems</u>
Manipulating: Equation 5x + y = 9
- Subtract 5x on both sides: y = 9 - 5x
<u>Step 3: Redefine Systems</u>
y = 9 - 5x
10x - 7y = -8
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>x</em>: 10x - 7(9 - 5x) = -8
- Distribute -7: 10x - 63 + 35x = -8
- Combine like terms: 45x - 63 = -8
- Add 63 on both sides: 45x = 55
- Divide 45 on both sides: x = 11/9
<u>Step 5: Solve for </u><em><u>y</u></em>
- Define equation: 5x + y = 9
- Substitute in <em>x</em>: 5(11/9) + y = 9
- Multiply: 55/9 + y = 9
- Isolate <em>y</em>: y = 26/9
To get the answer divide 4/5 by 1/10.
(4/5) / (1/10) = 4/5 * 10/1
4/5 * 10/1 = 40/5
40/5 = 8. There are 8 tenths in 4/5.
